I think S. Roe did a dyno test of a stock engine in and out of the car. He came up with a 12% loss. At the sametime each car is going to be VERY different.
Some may have 6th gear removed, dry sump and reduction pullies etc. These would certainly reduce engine drag and increace WHP without increasing BHP.
Bottom line, each component of the car will have its own loss factor and I think 12% loss is probably pretty close for a stock Viper engine/transmission.
